COMPOUND METAL-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 434,231, dated August12, 1890.

Application filed February 13, 1890. Serial No. 340,282. (No model.)

' To all whom it may concern:

Be is known that I, EzRA STILLMAN BAB- COCK, of \Valworth, in the countyof Valworth, and in the State of Wisconsin, have invented certain newand useful Improvements in Compound Metal-\Vorking Machines and I dohereby declare that the following isa full, clear, and exact descriptionthereof.

My invention relates to compound metalworking machines; and it consistsin certain peculiarities of construction, as will be fully set forthhereinafter and subsequently claimed.

In the drawings, Figure 1 is a side elevation of my improvedmachine,partly broken away to better illustrate the construction. Fig. 2 is avertical transverse section on the line 2 2 of Fig. 1. Fig. 3 is a likesection on the line 3 3 of Fig. 1, showing also a broken portion of thepunch-supporting shell. Fig. 4 is a transverse section on the line 4 4of Fig. 5. Fig. 5 is a horizontal section on the line 5 5 of Fig. 1, andFig- 6 is a like section on the line 6 6 of Fig. 1.

My present invention is, in part, an improvement on the device patentedto me Feb ruary 14, 1888, and numbered 377,976, and, like that, combinesa vise with a punching and shearing machine, but differs from saidmachine in details of construction, as hereinafter pointed out.

A is the stationary standard of my machine, having a flange a, by whichit may be suspended from a bench .when used in a vertical position, andabove this flange is the head B, containing one jaw of the vise, theupper part of said head terminating in a vertical face @1.

C is the swinging standard, having a head D, both heads B and D beinglongitudinally slotted or cut out centrally, as shown at g h, but thehead D being open at the top and only rising to the height of thecut-out portion or slot of the head B. As in my prior patenthereinbefore named, the swinging standard 0 is pivoted at 1) between apair of bearing-straps E E, which are themselves socured to thestationary standard A between the lugs (Z (Z by a bolt 0. The side wallsof the two heads B D have opposing V- shapcd concave faces ff, andfitted in the slots 9 h is a sliding head F, which has a V- shapedconcave serrated face 1', the said head F having a longitudinalscrewthreaded bore f for the reception of one end of a screw G. In myprior patent just named the screw was movable longitudinally and itsforward end was secured to the rear end of the sliding head; but in mypresent device the screw G is formed with a solid collar is, fitting ina seat in the end wall of thehead D, the outer end of the screw fromthis point and the bore in the said end wall through which it passesbeing smooth, and there being another collar 10 secured to said smoothend just outside said end wall, so that as now constructed, when saidscrew G is turned by its bar j or other hand device, the sliding head Fscrews upon or from the screw (according to which way the latter isbeing revolved) instead of moving with the said screw longitudinally, asheretofore. Further, in my present device the sliding head F is providedwith laterallyprojecting base-flanges n n on each side, which engagewithlongitudinal grooves o 0" at the base of the side walls of the slot h inthe head D, to prevent said sliding head F from rising from place whenit is wholly within the open-topped slot hin the said head D, and theother vertical-faced jaw e of the vise is formed solidly with said headF in my present device, the transverse ends of said vise-jaw e restingon top of the side walls of the head D and projecting beyond. them, allas best shown in Fig. 2.

The base of my machine is formed, as before, with two parallelhorizontal arms I and J, the former extending from the standard A andrigidly united at that end by a piece II, having projecting ears 7t 70,said piece and ears being flush with the outer edge of the stationarystandard A, so that the device may be placed horizontally of itsgreat-est length on a bench when more convenient to operate it in thisposition than in the vertical position shown in Fig. 1. The swingingstandard 0 projects below the bottom line of the arms I and J, and isbifurcated to receive one end of a link K, pivoted at m to saidstandard, the other end of said link being pivoted at m to thesimilarly-bifurcated eccentric-head n of a lever L, which head is inturn pivoted at 29 between the arms I and J.

M is a bell-crank-shaped detent journaled on a shaft or pin g, whichextends through the said arms I and J adjacent to the piece II, and whenmy machine is to be used as a vise the detent M is turned, as shown inFigs. 1 and 6, with the end of the long arm of said bell-crank pressingagainst the adjacent edge of the swinging standard C; but when themachine is to be used for punching or shearing, then the lower or shortarm of the detent is moved and the long arm thrown up and back againstthe piece H, out of the way of the swinging standard.

The punching device in my present machine is constructed as follows: Theupper part of the stationary standard A, just below its head B, isgrooved out for the reception of a circular plate N, provided near itscircumference with a series of holes 1, t 25 t of different diameters,and below this groove there is secured by screw-bolt u the lower flanger of a supporting-shell O, the upper portion of which is offset, asshown in Figs. 1 and 5, so as to furnish space between its inner surfaceand that of the standard A for the metal to be punched, saidupperportion having two rearward-extendin g wings s 8, having horizontalgrooves s s in their upper inner rear surfaces, while the front or innerwall of said shell 0 is provided with aholet' therethrough for theadmission of the punch P, which latter is secured by a set-screw w inthe stock Q, which in turn is pivoted by a bolt 00 to the standard 0,the end of said stock Q being rounded and fitting within a correspondingrecess 0: form ed in said standard, which latter is further out out orrecessed, as shown at 00 for the reception of the described upperportion of the shell 0, the rear wings s sof which projectover and restupon the top edges of the described bearing-straps E E, as best shown inFig. 4. It is designed to use a series of these punches P correspondingto the diameters of the holes 25 t in the circular plate N, which plateis turned around within its groove to bring the hole 15 of desireddiameter opposite the hole 7) in the shell 0 for use in connection withthe particular punch P to be used at any time; and for the purpose ofsteadying the stock Q'and insuring that the punch I shall always beproperly guided to place, the said stock Q is provided with trunnions s.9 that tit and move in the described grooves s s in the rear side wingss s of the supportingshell O.

R R represent the shearing-blades of my machine, which are secured bybolts g g within suitable recesses z a formed in the standards A and O,as shown in Fig. 1, the blades in this present case diifering from thosein my aforenamed prior patent, in that, whereas they were formerly setwith practically Vertical cutting-edges, (in the position of the machineshown in Fig. 1,) they are now formed with inclined opposingcutting-edges nearest together at the top and with the space normallybetween them increasing regularly from top to bottom, which gives abetter out than the former arrangement. As in my said prior patent, allof the parts are operated by the lever L, which brings the swingingstandard 0 and its attachments against the stationary standard A, sothat the metal being worked can be held in the vise or punchedorsheared, as desired, by a single movement of the said lever, while thepresent construction of the vise enables the upper vertical-faced jaw,which is connected to the swinging standard, to be adjusted, which is agreat improvement over the former construction, and at the same time theconcave faces of the vise can also be adjusted, and the presentconstruction of the punching device insures better results with greaterconvenience than formerly.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a compound metal-working machine, the combination of astationarystandard having a fixed vertical-faced vise-jaw at its upperend, and aswinging standard pivotally connected to the stationarystandard and having a vertical-faced vise-jaw at its upper endindependently movable relative to its movable supporting-standard, withan operating-lever having an eccentric-head pivoted to the base-frame ofthe machine and united by a link to the lower end of the said swingingstandard, substantially as set forth.

2. In a compound metal-working machine, the combination of a stationarystandard having stationary vertical-faced and concavefaced vise-jaws atits upper end and a swinging standard pivotally connected to the stationary standard and having vertical-faced and concave-faced vise-jawsat its upper end movable independently of their movablesupportingstandard, with an operatinglever having an eccentric-headpivoted to the baseframe of the machine and linked to the lower end ofthe swinging standard, substantially as set forth.

3. In a compound metal-working machine, the combination of a stationarystandard, a swinging standard pivoted thereto, and an operating-leverhaving aneccentric-head pivoted to the base-frame of the machine andlinked to the lower part of the said swinging standard, with a pair ofshearing-blades secured to the said standards and having inclinedopposing cutting-edges nearest together at the top and with the spacenormally between them increasing regularly from top to bottom,substantially as set forth.
